I had Patrick install a new natural gas furnace in my place in April. Their quote was maybe 5-7%…read morehigher than the much larger competing HVAC company, but I like the idea of giving business to smaller business owners. CAS handled the install in 1 day, easily. About 9 months later in late December, I woke up early in the morning to a cold house. Seems one of the wires on the igniter in the unit was faulty/loose (manufacturer issue, no installer). I called Patrick, and it went straight to v-mail. After leaving a message, I started to wonder if I shouldn't have gone with a larger company with more comprehensive customer support. Well, within 60 seconds of leaving the message I got a call back, and within 20 minutes, a very friendly mechanic was in my basement. He fixed the ignition error problem at no cost, and even took a quick peak at my gas fireplace that had been having some issues. Speaking as both a customer, and also a contractor - 10/10 experience.

Our furnace started blowing tepid air on a weekend day. When we called our propane company to…read morerequest service, they sent out a tech from Comfort Air Services. The tech told us that the heat exchanger was covered in soot and could no longer deliver hot air. We were told that our old furnace needed to be replaced. This was not a surprise since the unit was 20 years old. Patrick reached out to us with a quote to replace the furnace including a new whole house humidifier at our request. We also asked him to replace our 20 year old A/C unit with a new heat pump which he did. The furnace was replaced the next day along with a new programmable thermostat. The heat pump took another week or so to complete due to wait time on some parts that had been ordered. The very next day after installation we noticed that the time on the new thermostat had jumped five hours ahead which threw our heating schedule off. Three members of our family reprogrammed the thermostat to the correct time after it had repeatedly jumped five hours after each reprogramming. Clearly we had a defective unit since the clock continued to jump ahead on its own by five hours. We relayed this information to Patrick who was not convinced that we had a defective thermostat, so he came out to reprogram it again himself. The T-stat clock jumped ahead five hours on its own after Patrick had left. We called him with this news and he finally ordered a new thermostat and replaced it about two weeks after the initial installation. All this frustration could have been avoided if he had believed us initially and ordered a new thermostat sooner.
